Interior and Exterior Coating Specifications for Plastic Components
Weathering, thermal cycling and chemical exposure differ sharply between interior and exterior service. Building a specification that matches the environment.
Soft-Touch Coatings on Plastics: Why They Fail and How to Qualify Them
Soft-touch finishes degrade in ways hard coatings do not: tackiness, hydrolysis and chemical attack from skin contact. What to test before specifying one.
Coating Adhesion on Polyolefins: Primer, Pretreatment, or Both
Polyolefins reject coatings for a physical reason that primers and pretreatment address differently. Choosing between them, and when the answer is both.
Polycarbonate and Acrylic Hardcoats: Abrasion, Chemicals, Weathering
Hardcoat chemistries, application methods, adhesion and testing for polycarbonate and acrylic parts, plus the failure modes to design out before qualification.
Conductive, EMI-Shielding & Anti-Static Coatings for Plastic Housings
Conductive, EMI-shielding and anti-static coatings for plastic housings: resistance classes, coating options, adhesion and pretreatment, masking, testing and specification.
Coating Defects on Molded Plastic Parts: Craters, Fisheyes and More
How to diagnose craters, fisheyes, orange peel, blush, pinholes, dry spray and solvent stress cracking on painted injection-molded parts, and how to keep them from coming back.
Liquid, Powder or UV-Cure: Selecting a Coating Process for Plastics
Three coating processes with different temperature limits, cure mechanisms and geometry constraints. Matching the process to the substrate and the requirement.
