    It is suggested that unsaturated polyester is usually miscible with styrene and crosslinked and solidified under the action of peroxide initiator and drilling initiator

    The thick coating with high quality and strong decorative effect can be obtained

    The reaction mechanism is that the active radicals promote the crosslinking reaction of linear unsaturated double bond C = C in the unsaturated polyester and solidify the film

    Unsaturated polyester coating is a two-component coating system, which is composed of film-forming component and active reaction component

    (1) The film-forming components are composed of pigment, unsaturated polyester resin, styrene monomer, polymerization inhibitor and reaction accelerator

    (2) The active reaction component is initiated by peroxide Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces

    Each ceramic piece has raised characteristics

    Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller

    At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role

    The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1

    Roller coating in extremely harsh working environment 2

    The belt joint is not suitable for fixing with iron buckle; 3

    It is suitable for leather Paint Home News: unsaturated polyester and styrene are usually mutually soluble, under the action of peroxide initiator and drilling initiator, cross-linked curing occurs

    The thick coating with high quality and strong decorative effect can be obtained

    The reaction mechanism is that the active radicals promote the crosslinking reaction of linear unsaturated double bond C = C in the unsaturated polyester and solidify the film

    Unsaturated polyester coating is a two-component coating system, which is composed of film-forming component and active reaction component

    (1) The film-forming components are composed of pigment, unsaturated polyester resin, styrene monomer, polymerization inhibitor and reaction accelerator

    (2) The active reaction component is composed of peroxide initiator and reactive solvent (adjusting the proportion of sea complex)

    The thick coating paint with the reaction curing unsaturated polyester as the film-forming material is widely used in the kitchen furniture manufacturing industry for its excellent water resistance, wear resistance, bright and full appearance

    In addition, the reaction with peroxide should be avoided in the selection of pigment for the unsaturated polyester paint

    In addition to reaction curing type unsaturated polyester, there are also radiation curing type unsaturated polyester products at present

    The UV curing and electron beam curing coatings can be prepared by adding appropriate photoinitiators to the unsaturated polyester, which can be solidified into films in an instant

    The curing mechanism is that under the irradiation of ultraviolet and electron beam, the photosensitizer is broken down into active radicals, which makes the polymer compound cross-linked and solidified

    The polymer compound mentioned here can be unsaturated polyester or acrylic oligomer

    The formulation and reaction mechanism of radiation curing coatings are complex

    The formulation designer must consider many factors such as pigment, photosensitizer and radiation curing system when designing the formulation

    At present, the radiation curing unsaturated polyester coating is mainly used in flat coating (wood paint, home finish, etc.), and the application of curved surface coating is still limited
