1. 聚氨酯稀释剂 Polyurethane diluentProduct

DreamThinner 10:聚氨酯稀释剂是配合聚氨酯基础树脂混合使用，可以降低固化体系粘度，增加流动性，延长使用寿命，便于大面积施工；改善了操作性的同时，又不影响固化物的基本性能。 Polyurethane diluent is mixed with polyurethane base resin to reduce the viscosity of the curing system, increase flowability, extend service life, and facilitate large-scale construction; Improved operability without affecting the basic properties of the cured product

2. What is adhesion?

Adhesion is the firmness of theDreamThinner 10paint layer and the surface of the painted object through the action of physical or chemical forces.聚氨酯稀释剂 Polyurethane diluent Adhesion is the most important indicator for evaluating one聚氨酯稀释剂 Polyurethane diluentor聚氨酯稀释剂 Polyurethane diluenta 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. 聚氨酯稀释剂 Polyurethane diluentWhat is adhesion?

1）DreamThinner 10 Good adhesion can effectively block the penetration of the external electrolyte solution into the matrix, and delay the formation of interfacial corrosion;

2）Strong adhesionDreamThinner 10can 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.

"Polyurethane thinner is specially used in the construction process of polyurethane paint. It can adjust the construction viscosity of the paint, facilitate construction, adjust the drying rate of the paint, have good wettability to the substrate, clean spray guns, spray cans, etc. Add An appropriate amount of diluent can adjust the viscosity of polyurethane paint to the corresponding range, making construction easier.
