METHOD AND DEVICE FOR COATING A SUPPORT USING A CROSSLINKABLE SILICONE COMPOSITION

WIPO Patent Application WO2000056468

A9

The invention concerns a method for continuous coating of a paper strip or textile material support with a silicone composition, comprising at least a POS A with SiVi or SiOR groups, a POS B with SiH groups and a (hydrosilylation or dehydrogenation-condensation) catalyst C and not corresponding to a LTC/FC silicone system, said method comprising the following steps: step 1 which consists in providing conditions for homogeneously mixing constituents A, B, C such that the resulting homogeneity represents a DCS signature comprising a Gaussian peak for which the end-of-peak temperature T3 ranges between a value higher than 110 DEG C to 200 DEG C, said conditions requiring very accurate means for measuring the constituents, means for pre-mixing the constituents other than C and means for homogeneously mixing C with the pre-mixture(s) produced; step 2 which consists in feeding the homogeneous mixture to the coating site; step 3 which consists in coating the support with the homogeneous mixture; and step 4 which is a curing step, in particular heat-curing.
