Advantages:
--Easy to operate with single composition;
--Excellent elasticity, adhesive for rubber regeneration granules;
--100% solid content, and no solvents and no volatility
--Containing anti-aging agent, and anti-weathering agent;
--able to conglutinate multi-kinds of elastic materials;
--No harmful to environment.
Way of solidification:
It usually solidify through humidity reaction in atmosphere, usual at low temperature and low humidity and slow in reaction.
Chemical stability
Stable in as follows: fresh water, sea water, lime water, drainage, diluted acid, dilute base, fuel, vegetable oil and fat oil and etc. unstable in organic acid, concentrated base and solvents.
Way of application:
Surface adhesive 9%;
Medium layer adhesive 7%;
Bottom adhesive 8%?
Security: As for the information and suggestions for security and storage and processing of some chemicals, you'd better refer to the latest data list for security including physic, ecological, and toxicological and other data.
