1. 聚硅氧烷面漆 Polysiloxane top coatProduct

DreamDur 560: Acrylic polysiloxane coating is a high-performance, high solid content coating that complies with all current VOC regulations and does not contain heavy metals such as lead and chromium, and does not contain isocyanates. The resistance to yellowing and powdering is significantly superior to typical polyurethane coatings. At the same time, it has the same corrosion resistance and mechanical properties as epoxy resin coatings, but its light and color retention performance is even better

2. What is adhesion?

Adhesion is the firmness of theDreamDur 560paint layer and the surface of the painted object through the action of physical or chemical forces.聚硅氧烷面漆 Polysiloxane top coat Adhesion is the most important indicator for evaluating one聚硅氧烷面漆 Polysiloxane top coator聚硅氧烷面漆 Polysiloxane top coata coating system. Is the premise of paint film with a series of properties. The methods of adhesion test include: circle method, grid method, drawing method, twist method and ASTM, etc

2. 聚硅氧烷面漆 Polysiloxane top coatWhat is adhesion?

1）DreamDur 560 Good adhesion can effectively block the penetration of the external electrolyte solution into the matrix, and delay the formation of interfacial corrosion;

2）Strong adhesionDreamDur 560can greatly prevent the diffusion of corrosion products- -metal cations to the cathode area through the side of the phases;

4. Graph method

Basis: color paint and varnish marking method adhesion test GB / T 9286-1998, "marking method" also called "X method", hundred grid test method, applicable to assess the attachment ability of coating, is a commonly used evaluation method at home and abroad

4.1. Grid marking steps

1）1) according to the thickness of different knife saw grid: (ordinary informal test can be replaced by paper cutter), membrane thickness: 0~60 μ m, tool spacing 1mm, membrane thickness: 61~120 μ m, tool spacing 2mm, membrane thickness: 121~250 μ m, tool spacing 3mm

2) Pull the special tool parallel to the grid plate for 3-4cm, there are 10 cuts, should ensure that each one is cut through the paint film to the substrate;

3) Then use the same method to be perpendicular to the former, with the same 10 cuts;

4) In this way, when many small squares are formed, use soft brush to form each diagonal line along the grid map, gently sweep forward and back several times to remove dust, and then paste the tape (it is recommended to use 3M tape), and ensure that the tape and the experimental area comprehensive contact, can be rubbed back and forth to make good contact, and then quickly pull open;

5) Use the visual or magnifying glass to compare the standard and the illustration

The table gives the six levels of classification for the general use of the first three levels is satisfactory. The first three levels are also used if the assessment is passed / failed.

The following is the technical standard reference diagram:

4.2. Explanation

ISO level: 0 = ASTM level: 5B, the edge of the incision is completely smooth, the grid edge is not any peeling.

ISO level: 1 = ASTM level: 4B, there are small pieces of peeling at the intersection of the incision, and the actual damage in

ISO level: 2 = ASTM level: 3B, the edge or intersection of the incision is peeled off, the area is greater than 5%~15%.

ISO level: 3 = ASTM level: 2B, partial strip or whole strip, or part of the grid. The area of peeling off exceeds 15% to 35%.

ISO level: 4 = ASTM level: 1B, the incision edge or some square part, the area is greater than 35%~65% of the grid area.

ISO grade: 5 = ASTM grade: 0B Pieces of paint fall off at the crossed edge and intersection point, and the total area of shedding is more than 65%. Note: BaG test qualified when grade 4B and 5B.

Polysiloxane topcoat is a two-component, isocyanate-free, high-weather-resistant, high-solids, heavy-duty anti-corrosion topcoat composed of organic/inorganic polymers. The VOC content is well below the limits of international environmental regulations. Paint The layer has excellent salt spray resistance, gloss retention, and color retention. Compared with general traditional topcoats including acrylic topcoats and polyurethane topcoats, the long-term yellowing resistance and powdering resistance are significantly improved. Mechanical Better properties: the coating is non-flammable and flame retardant; the coating has excellent pollution resistance, abrasion resistance, scrub resistance, surface lotus leaf effect and self-cleaning function, and is resistant to water and salt solutions, acidic salt solutions, and alkaline salt solutions , petroleum products, and organic solvent splashes; can adhere to all surfaces such as steel, cast iron, aluminum alloy, stainless steel, ceramics, concrete, wood, and glass."
