Trimethyl Propane Di-allyl Ether

Trimethyl propane di-allyl ether is used in direct gloss polyester coatings, mainly wood coatings but also for putties in automotive repair, to improve surface hardness. This liquid product contains two allyl groups and one hydroxyl group. It is used in unsaturated polyesters giving excellent coatings for furniture with high build and gloss. Formulations are available for UV curing and peroxide curing.

TMPDE can decrease the restraining effect of oxygen.

Applications :
1. Unsaturated Polyester Resin (PE):
Air-drying unsaturated polyester (PE) resin without wax can be obtained by introducing TMPDE.
2. Alkyd Resin:
TMPDE can improve water resistance, drying and color of alkyd resin.
3. Water-based Resin:
In water, TMPDE can dissolve or disperse alkyd and polyester resins, thus improving their drying ability.
4. Others:
TMPDE can be applied to many other fields, such as UV curable acrylate, polyurethane and epoxy and polyacrylate thickener.
