Abstract
An unsaturated silane is used in methods and compositions for improving the gloss, matte and ultraviolet-curing efficiency properties of ultraviolet-curable compositions, adhesives and sealants.
Claims28
A composition, comprising:
- (I) a silane of Formula I:
- wherein:
- i) Y is a functional group capable of reacting under ultraviolet irradiation in the presence of a photoinitiator;
- or
- Y is a saturated functional group capable of coupling with radicals;
- ii) X is —C1-60 alkyl;
- iii) A and B are independently selected from:
- —X—Y wherein X and Y are as defined in (i) and (ii) above;
- —C1-20 alkyl;
- and
- —OR1 wherein R1 is selected from the group consisting of H and —C1-6 alkyl;
- iv) C is —OR1 wherein R1 is selected from the group consisting of H and —C1-6 alkyl;
- (II) a photo initiator;
- and
- (III) ultraviolet-curable resin.
