One kind in 75% isocyanate-terminated polyurethane special curing agent, the trade mark of such as nine yuan of production in Shanghai is JYL-20, JYL-
33 product.
Described catalyst is organic tin catalyst, specially dibutyl tin dilaurate, is the market universal product, board
Number be T12, such as connection scape chemistry T12 products.
Described solvent is that one or more esters combined in ethyl acetate, methyl acetate or dimethyl carbonate are molten
Agent, solvent is the market universal product, and selection moisture is less than 0.03% high-class product.
The present invention compared with the existing technology, has prepared steady quality with simplest process conditions, and cost is lower and energy
Meet the monocomponent adhesive of the different field requirement such as automobile, household, compound, raw material range of choice is cheap easy than wide
, quality control is easy；Production process control is simple, and energy consumption is lower；Production process is more environmentally-friendly.
