Product Description

 

Solvent based adhesive curing agent additive

 

 

 

TPUA-ACFN (Non Yellowish) (Similar to RN)

 

 

Application
After the addition of TPUA-ACFN (NON YELLOWISH), the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only its content of rubber, but also by the other ingredients of the formulation (e.g. resins, antioxidants, solvents, etc.) If the adhesive is not used within this period, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs.
 
 
Description
The almost colorless TPUA-ACFN (NON YELLOWISH) is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber; owing to TPUA-ACFN (NON YELLOWISH) features good photo-resistance, it is particularly suitable for light-color polyurethane adhesive system. Because the solvent is ethyl acetate, TPUA-ACFN (NON YELLOWISH) can be used in those countries where the use of methylene chloride is restricted.
 
 
Typical Properties
Chemical composition
Solution of approx .27 %
Polyisocyanate in 73% ethyl acetate
Intrinsic color
almost colorless to light-color clear liquid
NCO content, %by weight
6.8±0.2
Solubility
Soluble in various esters, ketones and aromatic solvents
Storage stability
Reacts readily with moisture; for best performance it should be kept dry and stored at temperatures between(5oC~32oC)
 
 
Performance
The Film of adhesive and coating film mixed by TPUA-ACFN (NON YELLOWISH), is difficult to become yellow after exposure to UV light and heat. So TPUA-ACFN (NON YELLOWISH) shows good bonding strength in PVC with much plasticizer, SBR with plenty of oil, coasting leather, silk and so on.
 
 
Suggested Additions
For Curing adhesive of 100 parts by weight (p.b.w) based on:
 
Graft - Choloroprene rubber
(Rubber content approx. 16%)
3-5 p.b.w. TPUA-ACFN (NON YELLOWISH)
Choloroprene rubber
(Rubber content approx. 20%)
5-7 p.b.w. TPUA-ACFN (NON YELLOWISH)
Hydroxyl polyurethane
(Rubber content approx. 15%)
3-5 p.b.w. TPUA-ACFN (NON YELLOWISH)
 
 

 

 

TPUA-AC528 (Similar to RC) (Good Heat Resistance)

 

 

Application
After the addition of TPUA-AC528, the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only by its content of rubber, but also by the other ingredients of the formulation (e.g. resins, antioxidants, solvents, etc.) If the adhesive is not used within this period of time, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs.
 
 
Description
The almost colorless TPUA-AC528 is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber; owing to TPUA-AC528 has the feature of good photo-resistance, it is particularly suitable for light-color polyurethane, adhesive system. Because the solvent is ethyl acetate , TPUA-AC528 can be used in those countries where the use of methylene chlorides is restricted.
 
 
Typical Properties
Chemical composition
Approx.25% aromatic polyisocyanate in 75% ethyl acetate.
Intrinsic color
Almost colorless liquid
NCO content, %by weight
5.8±0.2
Solubility
Soluble in various esters, ketones and aromatic solvents
Storage stability
Reacts readily with moisture; for best performance it should be kept dry and stored at temperatures betweens 5oC and 32oC
 
 
Compatibility With Solvents
TPUA-AC528 can be diluted with anhydrous and alcohol-free ethyl acetate, dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene, and other similar solvents. The addition of relatively by using lager proportions of the solvents mentioned above.
 
 
Suggested Additions
For Curing adhesive of 100 parts by weight (p.b.w) based on:
Graft - Choloroprene rubber
(Rubber content approx. 16%)
3-5 p.b.w. TPUA-AC528
Choloroprene rubber
(Rubber content approx. 20%)
5-7 p.b.w. TPUA-AC528
Hydroxyl polyurethane
(Rubber content approx. 15%)
3-5 p.b.w. TPUA-AC528
 
 
 

 

TPUA-C43F (Similar to RC)

 

 

Description
The almost colorless TPUA-C 43F is designed as curing agent for adhesives based on hydroxyl polyurethane, natural and synthetic rubber. Because the solvent is ethyl acetate, TPUA-C 43F can be used in those countries where the use of methylene chloride is restricted.
 
 
Typical Properties
Chemical composition
Approx 35% solution of an aromatic polyisocyanate in ethyl acetate.
Intrinsic color
Almost colorless liquid
NCO content, %by weight
8.4±0.2.
Solubility
Soluble in various esters, ketones and aromatic solvents.
Storage stability
Reacts readily with moisture; for best life it should be kept dry and stored at temperatures between 5 oC and 32 oC
 
 
Compatibility With Solvents

TPUA-C 43F can be diluted with anhydrous and alcohol-free ethyl acetate, dichloropropane, trichloroethylene, acetone, methyl ethyl ketone and toluene, among other solvents. When added in relatively large proportions aliphatic hydrocarbons can cause turbidity; but can be re-dissolved by using earger proportions of the solvents mentioned above.

 

 

 

TPUA-E33D (Similar to RFE)

 

 

Application
After the addition of TPUA-E33D, the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only by its content of rubber but also by the other ingredients of the formulation (e.g. resins, antioxidants, solvents, etc.) If the adhesive is not used within this period, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs.
 
 
Description
The light-color TPUA-E33D (similar to Desmodur RFE) is an established, universal curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber. TPUA-E33D can be used instead of TPUA-13-F 25G . RFE is even more satisfactory from the aspect of industrial hygiene.
 
 
Typical Properties
Chemical composition
Contains 27% thiophosphoric-tris-(p-isocyanato-phenyl ester) and 73% ethyl acetate.
Apperance
Clear yellow to brownish liquid.
NCO content, %by weight
7.2±0.2.
Solubility
Soluble in acetone, toluene and methyl ethyl ketone and aromatic solvents.
Storage stability
Reacts readily with moisture; for best performance it should be kept dry and stored at temperatures between 5 oC and 32 oC
 
 
Compatibility With Solvents
TPUA-E33D can be diluted with anhydrous and alcohol-free ethyl acetate dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene, and other solvents. The addition of relatively large proportions of aliphatic hydrocarbons can cause turbidity; but the solution of natural rubber in aliphatic hydrocarbons show good compatibility with TPUA-E33D, in the absence of other solvents.
 
 
Performance
TPUA-E33D shows good bonding strength in PVC with much plasticizer, SBR with plenty of oil, coating leather, silk and so on.
 
 
Suggested Additions
For curing adhesive of 100 parts by weight (p.b.w.) based on:
Graft - Choloroprene rubber
