UV-CURABLE SILICONE COMPOSITION, CURED PRODUCT, AND SILICON WAFER COATING AGENT
Document Type and Number:
WIPO Patent Application WO/2024/038670
Kind Code:
A1
Abstract:
A composition containing (A) (i) and/or (ii) (i) polysiloxane (1) AR1
2Si(OR1
2Si)mOSiR1
2A (1) (ii) polysiloxane (2) (R1
3SiO1/2)p(A(3-a)R1
aSiO1/2)q(SiO4/2)r (2) (R1 is a monovalent hydrocarbon group, A is an alkenyl group, m is 1-10,000, p > 0, q > 0, r > 0, p + q + r = 1, a is 1 or 2), (B) hydrogen polysiloxane (3) (R1
3SiO1/2)s(H(3-b)R1
bSiO1/2)2-s(HR1
1SiO2/2)t(R1
2SiO2/2)u (3) (R1 is as above. b is 1 or 2, 0 ≤ s ≤ 2, 2 ≤ t + u ≤ 800, 0.6 ≤ t/(t + u + 2)
≤ 1.0), and (C) a platinum group catalyst activated by light of a wavelength of 200-500 nm, where (B) Si-H groups/(A) alkenyl groups = 0.8-4.0 (molar ratio), adheres well to metal silicon even without adding an adhesion aid.
