Properties and Usage:
PETMP (tetrakis (3-mercaptopropionic acid) pentaerythritol ester) has high stability and good solubility. Its chemical structure contains thiol and epoxy groups, so it has active functions and is widely used in many industrial fields.
1. As a hardener raw material for epoxy resin, its active groups can react with the double bonds in the epoxy resin to promote the curing of the resin and improve the strength and durability of the product. Used as raw material for polyurethane lenses and monomer for UV curing.
2. In metal surface treatment, PETMP is used to improve the adhesion of the coating and enhance surface protection performance. It is also widely used in structural adhesive products and UV protective coatings to provide products with excellent weather resistance and anti-aging properties.
3. As an intermediate in organic synthesis, it is used as a modifier and cross-linking agent in polymerization reactions such as UV coatings, inks, adhesives, etc., which can improve the performance of the product and enhance its durability.
4.PETMP is used as rubber accelerator. Its active groups can react with double bonds in rubber to form cross-linking bonds, accelerate the vulcanization speed and enhance the degree of vulcanization. This makes PETMP play an important role in the production of rubber products such as tires, seals, rubber tubes, etc.
Packaging specifications:
It is packed in 200kg or 250kg galvanized drum or plastic drum, and it can also be customized according to customer requirements.
Store in a dry, dark and well-ventilated place, away from fire and avoid impact. The storage period of the product at 30 °C is 6 months.
