Abstract
Process for the continuous coating of a strip of paper or of a textile support using a silicone composition, comprising at least one POS A containing SiVi or SiOR groups, a POS B containing SiH groups and a catalyst C (for hydrosilylation or for dehydrogeno-condensation) and not corresponding to an LTC/FC silicone system, the said process comprising the following steps: step 1 in which conditions for homogeneously mixing the constituents A, B and C are used such that the homogeneity obtained is reflected by a DSC signature comprising a Gaussian peak for which the peak end temperature T3 is in the range from a value above 110° C. to 200° C., the said conditions making use of means for very precisely metering the constituents, means for premixing the constituents other than C and means for homogeneously mixing C with the premix(es) prepared; step 2 of conveying the homogeneous mixture to the coating site; step 3 of coating the support with the homogeneous mixture; and step 4 of crosslinking, in particular with thermal means.
