Application

4-Hydroxybutyl acrylate is an organic compound with both hydroxyl and acrylic double bonds, mainly used in the coatings industry(especially automotive topcoats and UV curable coatings), adhesive fields, and can be used as an organic synthesis intermediate. ‌
Main application areas:
Paint industry:
Automotive topcoat: 4-Hydroxybutyl acrylate improves the scratch resistance, heat resistance, and impact strength of the paint film, widely used in original and repair paint formulations. ‌‌
UV curable coating: 4-Hydroxybutyl acrylate has a fast curing speed under 365nm UV light source, significantly improving the flexibility, chemical resistance, and weather resistance of the coating. ‌‌
Powder coating: 4-Hydroxybutyl acrylate optimizes flowability, reduce curing shrinkage to below 0.8%, enhance coating's corrosion resistance and heat resistance. ‌‌
Adhesive field:
As a functional monomer of polyurethane adhesive, the peel strength is increased to 8.5kN/m. ‌‌
4-Hydroxybutyl acrylate reduce curing shrinkage in epoxy resin system, and enhance adhesive strength, correction and durability. ‌‌
4-Hydroxybutyl acrylate can be used in UV adhesive and other UV curing systems to enhance low-temperature hardening and scratch resistance. ‌‌
Other applications:
As an organic synthesis intermediate, 4-Hydroxybutyl acrylate is used for polymer modification in laboratory research and chemical production
4-Hydroxybutyl acrylate can be used as raw material for water-based coatings, architectural coatings, and adhesives around displays, endowing materials with processing impact resistance and thermal shock resistance. ‌‌

Storage

Store in a cool, dry and ventilated place; Avoid high temperature and humid environments.
