摘要:
The present invention relates to a polyester-fiber-treatment agent that can impart smoothness and flexibility to polyester fiber at the same time that it also equips the polyester fiber with nonflammability. The treatment agent for the polyester fiber is based on an organosilicon compound that contains an organic group comprising a bromine-containing organic group bonded to silicon via carbon where the organosilicon compound has a bromine content of at least 5 weight percent.
摘要:
An organopolysiloxane graft-type polyester is prepared by reacting, in the presence of an effective amount of a hydrosilylation catalyst, a polyester containing at least one alkenyl group and having no unsaturated terminal groups, said polyester having a number average molecular weight of about 500 to about 5,000, and an organopolysiloxane containing one hydrosilyl group. The organopolysiloxane graft-type polyester has excellent compatibility with polyesters and can improve the surface smoothness and hydrophobic property of the polyester when modified therewith.
摘要:
A fiber treating agent which is a silicone modified polyester in which a polyester has a polyoganosiloxane grafted thereto. The grafted polyester is the reaction product of an allyl ether containing polyester and a polyorganosiloxane wherein at least one of the silicon atoms of the polyorganosiloxane has a hydrogen atom attached thereto. Preferably, the hydrogen atom is attached to one terminal end of the polyorganosiloxane. The reaction product is modified by reacting the reaction product with a polycarboxylic anhydride, and the amine salt of the modified reaction product may be formed by reacting the modified reaction product with an aminoalkylalkoxysilane. Methods of treating fibrous materials are also described.
摘要:
Films and coatings formed from a specified class of organosiloxane/urethane copolymers are unique by virtue of their high permeability to volatile ingredients in the form of aqueous compositions and their inertness to the ingredients of these compositions. Containers wherein at least a portion of the walls comprise films or coatings formed from these copolymers are used to achieve the controlled release of volatile fragrances and biologically active agents from aqueous compositions confined within the container into the adjacent atmosphere.
摘要:
Room temperature-curable organopolysiloxane compositions are made from essentially linear organopolysiloxanes having hydroxyl or hydrolyzable end groups, a crosslinking agent, a filler, optionally a curing catalyst, an unsaturated ester having at least ten carbon atoms in the unsaturated fatty acid component of the ester, and a photosensitizer. These compositions cure to elastomeric materials which do not soil on the surface or the surrounding areas of the substrate in contact with the cure product. The adhesion of these cured products is not reduced.
摘要:
Room temperature-curable composition made from a silicone-modified polyether containing silyl end groups having hydrolyzable groups and ester provide a cured silicone product which does not have a tacky surface. Adding a sensitizer to the composition increases the reliability of the surface to be void of tack. These compositions have less dirt pickup.
摘要:
A room temperature vulcanizable polyorganosiloxane composition which cures to products, such as silicone rubber, which do not soil easily are made from mixing silanol containing polyorganosiloxane, ketoxime silicon compounds such as organotriketoximosilanes, and organotitanates.
摘要:
A cured product which resists soiling under outdoor exposure obtained from a mixture of a silanol containing polyorganosiloxane having at least one silicon-bonded oxyalkylene radical of the formula --R.sup.1 O(R.sup.2 O).sub.n R.sup.3 and a curing agent.

摘要:
What is disclosed herein is a room temperature curable, one component epoxy resin modified silicone resin which has excellent heat resistance, adhesiveness to substrates, and is hard. The improvements in properaties are obtained by the use of epoxy fatty acid esters in the coating formulation.
摘要:
What is disclosed are room temperature curable silicone resins which have solvent, heat and weather resistance, mold release properties and water repellency in their cured state. Silicone resins are treated with alkoxylated siloxanes, alkoxysilanes and aminoalkoxysilanes to give these properties.
