Introduction
The water-based polymer adhesive used in the industrial thermal insulation coating formulation has low VOC, which is suitable for the indoor production equipment of industrial enterprises, and meets the on-site demand for coatings curing at room temperature and temperature curing in continuous production.
Application field
This coating formulation is mainly a water-based, one-component thermal insulation coating for the surface of industrial equipment.
Recipe details
Production Method
- According to the formula ratio, inject 10-15 parts of deionized water into the pre-mixing and dispersing tank, start the mixer, control the speed between 150 and 200r/min, add 1/2 total amount of inorganic pigment and filler dispersant, 1/ 2 Fully stir the total amount of wetting agent added.
