Adhesion Promoters ProductSelection Guide

UV CURE APPLICATIONS

CN-704

CN-704 is an acrylated polyester adhesion promoter thatprovides excellent adhesion to polyolefins, such as poly-ethylene and polypropylene. CN-704 is designed for UV/EB cured inks and coatings. Due to its low acid value, CN-704 can be used in formulations containing tertiary amines.Usage levels of 40-60% are recommended.

SR-9008

SR-9008 is an alkoxylated difunctional monomer devel-oped to assist adhesion of UV/EB cured inks and coatingsto glass surfaces. It is also an excellent choice for OPVapplications. SR-9008 features good weatherability andimpact strength. Usage levels of 5-10% are recom-mended.

SR-9012

SR-9012 is a trifunctional acrylate monomer that assistsadhesion of UV/EB cured inks and coatings to plastics,metal, and glass. Recommended usage levels are 5-10%.

SR-9016

SR-9016 is a metallic diacrylate adhesion promoter forUV/EB cure applications. SR-9016 is water soluble up to20 wt.%. This product promotes adhesion to metals,including steel, tin-free steel, brass, and aluminum. Usagelevels up to 5% are recommended.

CD-9050

CD-9050 is a monofunctional acid ester that promotesadhesion to metals, including aluminum, brass, steel, andtin-free steel. CD-9050 is an excellent choice for lowshrinkage. Due to its high acid value, this product is notrecommended for use in formulations containing ter-tiary amines. Usage levels of 3% to 12% arerecommended.

CD-9051

CD-9051 is a trifunctional version of CD-9050. CD-9051 offers the same adhesion promoting properties asCD-9050. However, due to its trifunctionality, CD-9051 provides faster cure response, greater hardness,and good water resistance. As with CD-9050, CD-9051is not recommended for use in formulations containingtertiary amines. Usage levels of 3% to 12% by weightare recommended.

CD-9052

CD-9052 is a trifunctional acid ester adhesion promoterfor UV/EB inks and coatings that offers exceptional curespeed. CD-9052 assists adhesion to difficult substrates,such as plastics, metals, and glass. CD-9052 is notrecommended for use in formulations containingtertiary amines. Usage levels of 3-12% are recom-mended.

PEROXIDE CURE APPLICATIONS

SR-633

SR-633 is a metallic diacrylate monomer, developed toassist rubber-to-metal adhesion in peroxide cureapplications. Recommended use levels are 4-10%.
