Abstract:
A combination of for surface treating powder is disclosed. The combination comprises a mixture of an organopolysiloxane (I) and organopolysiloxane (II), a mixture of an organopolysiloxane (I) and acryl/silicone copolymer (III) or a mixture of an organopolysiloxane (I), organopolysiloxane (II) and acryl/silicone copolymer (III) as defined herein. The organopolysiloxane (I) is represented by the following formula (1) R1a(OR2)bSiO(4-a-b)/2 with the subscripts “a” and “b” and groups R1 and R2 defined herein. The organopolysiloxane (II) is represented by the formula R3cR4dR5eSiO(4-c-d-e)/2 with the subscripts “c”, “d” and “e” defined and groups R3 and R4 defined herein, and group R5 being a silicone compound residue of the formula as defined herein.
