Dow DOW Multifunctional Auxiliary AMP-95 pH Regulator

Product Introduction
AMP-95 is a multifunctional additive widely used in latex paint. In the formulation, AMP-95 can be used as a dispersant to prevent secondary flocculation of pigments; at the same time, AMP-95 can also greatly improve the overall performance of coatings. The use of AMP-95 in different stages of paint manufacturing can provide the following performance improvements.

Purpose
Benefits of using AMP-95 in the grinding stage:
(1) When used in conjunction with traditional dispersants, the amount of dispersants can be reduced;
(2) Optimizing the dispersion of pigments;
(3) The foam is reduced due to the reduction of the amount of dispersant;
(4) Effectively control the pH value;
(5) Reduce formula cost.
The benefits of using AMP-95 in the paint mixing stage:
(1) Improve the performance of the thickener;
(2) Avoid using ammonia water to reduce the smell of paint;
(3) Improve the color rendering of the toning paste.
AMP-95 improves paint film properties:
(1) Improve scrub resistance and water resistance;
(2) Reduce corrosion and flash rust in tanks;
(3) Effectively reduce the odor of the system;
(4) It does not increase the volatile organic compounds (VOC) in the system.

When formulating a latex paint, the effect of dispersants and surfactants on the paint and its final properties are important considerations. The data in this technical specification shows that the use of AMP-95 can reduce the amount of additives used in many coatings, thereby reducing the cost of raw materials and improving the performance of coatings. Typical characteristics of V: ​​Neutralization equivalent: 93~97 Flash point: Open cup: 78°C; Closed cup: 83°C Specific gravity: 0.942 pH value: 11.3 (0.1 molar aqueous solution) Viscosity: 147 centipoise at 25°C; 10°C It is 561 centipoise; at -2°C, solidification surface tension: stock solution: 37 dyne/cm; 10% aqueous solution: 58 dyne/cm Suggested dosage: in the grinding stage: AMP-95 is used as a co-dispersant, the best The method of use is to replace 30% of the dispersed solids in the existing system.

Generally, the dosage of AMP-95 is 0.05% to 0.1% of the total formula. In the paint mixing stage: In a typical formula, in order to obtain the best pH stability, the neutralization degree of the thickener and the elimination of corrosion in the tank, the dosage of AMP-95 is 0.1% to 0.3% of the total formula In order to control flash corrosion, an additional 0.1% to 0.2% (according to the total amount of the formula) of AMP-95 should be added. AMP-95 can endow the latex paint with excellent pH stability. Ammonia is a weak amine and It is more volatile than AMP-95, so the pH stability of the ammoniated paint is poor, and the odor is heavy. The control of pH value is very important to the deployment of latex paint, because most paint configurations have a stable alkaline pH value to control the following properties: dispersion of pigments, stability of the system, corrosion of packaging barrels, and stability of viscosity . In addition, other commonly used amines and alcohol amines tend to cause yellowing of the paint film, but AMP-95 will not cause yellowing, which is especially important for most high-end paints.
