AMP 95
AMP™ is the premier, flagship product from ANGUS for paint and coatings. As a primary multifunctional amine, AMP offers more functionality, more flexibility, and more value than other amines. This product is sold as AMP-95, AMP-90 and AMP-75 with 5%, 10% and 25% water added respectively to the active.
Trusted by formulators worldwide for its neutralizing and multifunctional capabilities, AMP-95 works well as a co-dispersant and provides outstanding film properties in finished formulations. Key benefits include improved pH stability, excellent scrub-resistance, optimal color acceptance, improved gloss and outstanding hiding power.
AMP-95 is our premier primary amino alcohol, designed for use in all water-dilutable metalworking fluids, especially where a colorless product is required. AMP-95 is used worldwide, providing superior performance among commonly available amine products.
AMP-95® is widely recognized as a multifunctional additive for all types of latex emulsion paints. In a formulation, AMP-95 can be used as a powerful co-dispersant to prevent re-agglomeration of pigments. At the same time, AMP-95 will contribute significant
benefits to the overall performance of the coating.

The benefits and performance improvements made possible by AMP-95 in different stages of paint manufacture are:
AMP-95 in the Grind
- Reduces dispersant demand when used in
conjunction with conventional dispersants.
- Optimizes pigment dispersion.
- Reduces foam (through dispersant reduction).
- Provides effective pH control.
- Lowers raw material costs.
AMP-95 in the Letdown
- Improves thickener performance.
- Eliminates need for ammonia, resulting
in a lower odor paint.
- Improves color acceptance of shading pastes.
AMP-95 and Coating Performance
- Improves scrub, water, and block resistance
through formula optimization
- Reduces in-can corrosion
- Effective in low odor systems
commonly used paint additives, thereby lowering raw material costs while improving paint performance.
Recommended Use Levels
In The Grind
To take full advantage of AMP-95 as a co-dispersant, up to 30% of the existing dispersant solids can be replaced by an equal weight of AMP-95. This generally amounts to 0.05 to 0.1 percent ofAMP-95 on the total weight of the formulation.
In The Letdown
Typical formulations require 0.1 to 0.3 percent
(on total formulation weight) of AMP-95 for optimum
pH stability, for associative thickener neutralization
and to eliminate in-can corrosion. For control of flash
rusting,an additional 0.1 to 0.2 percent (on total
formulation weight) of AMP-95 may be required.

Advantages using AMP 95 :
> Eficient Pigment Dispersion
AMP-95 improves pigment dispersion in the
production of latex paints. Combining AMP-95
with a conventional anionic dispersant in a grind
paste is more effective than using any dispersant alone.
production of latex paints. Combining AMP-95
with a conventional anionic dispersant in a grind

AMP-95 enhances the performance of anionic
dispersants so that dispersant demand is reduced.
Six commonly-used dispersants were tested in
a typical dispersion. As shown in the table below,
small quantities of AMP-95 in a TiO2, calcined clay,
and calcium carbonate blend significantly reduced
dispersant demand. Specific dispersant requirements
vary with the pigment grade, type and lot.

Using AMP-95 in the grind produces a paint with
maximum hiding power, color acceptance and
stability at considerably lower anionic dispersant
levels than are normally required to achieve similar
results. AMP-95 also stabilizes the grind at a mildly
alkaline pH. This reduces the tendency for pigment
maximum hiding power, color acceptance and
stability at considerably lower anionic dispersant
levels than are normally required to achieve similar
results. AMP-95 also stabilizes the grind at a mildly
alkaline pH. This reduces the tendency for pigment
re-agglomeration or “shock” when the grind is added
to a moderately alkaline letdown.

> Reactive Pigment Stabilization
AMP-95 helps to stabilize some paint systems
containing reactive pigments such as zinc oxide.
Typical improvements are demonstrated in the
following photo; the addition of AMP-95
inhibited gelling even for paint subjected to heat aging.

> Film Performance
Most dispersants and surfactants contain 25 to 50%
non-volatile, hygroscopic components, which
remain in the dried paint film and contribute to
poor scrub resistance and water spotting.
Therefore, it is important to keep these
additives to a minimum. AMP-95 used in
conjunction with reduced levels of conventional
dispersants accomplishes this objective.
The results are improved scrub resistance,
water resistance, and reduced water spotting
of the paint film as illustrated below.
