Product Uses
After the addition of HARTDUR C528, 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.

Top quality low price made in china HARTDUR E333 for sale 

 

The light-color HARTDUR E333 is an established, universal curing agent for adhesive based onhydroxyl polyurethane, natural and synthetic rubber. HARTDUR E333 can be used instead of HARTDUR F256. HARTDUR E333 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

Intrinsic coloralmost colorless to light-color clear liquid
NCO%7.2 ± 0.2
SolubilitySoluble in various esters, ketones and aromatic solvents
Storage stability

Reacts readily with moisture; for bestperformance it should be kept dry and stored at temperatures between 5℃~32℃.

Comptibility with solvents: HARTDUR E333 can be diluted with anhydrous and alcohol-free ethylacetate dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene, and other solvents. The addition of relatively large proportions of aliphatic hydrocarbons can cause turbidity; but the solutions of natural rubber in aliphatic hydrocarbons show goodcompatibility with HARTDUR E333, in the absence of other solvents.


Applications: 

After the addition of HARTDUR E333, 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.

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. HARTDUR E333 Choloroprene rubber (rubber content approx. 20%): 5-7 p.b.w. HARTDUR E333 Hydroxyl polyurethane (polyurethane content approx. 15%):3-5 p.b.w. HARTDUR E333.
