Rheological Additive for Water-Based System

2018-08-18 06:01:34
Model NO.: BK-887L
BK-887L is a modified bentonite for water-based systems

1. Advantages:
☆ High gelling efficiency in water-based systems. Can replace traditional  cellulose ether thickening agent.
☆ Excellent thixotropy property, sag resistance and viscosity control.
☆ Prevent hard settlement of pigment/fillers.
☆ Ease of incorporation and Ease of dispersion.
☆ Suite to wide PH range.
☆ Good corrosion resistance and stable viscosity in different temperatures. Good bio-stability and heat resistance.
☆ Has apparent level limitation.Viscosity increases dramatically when exceeds certain amount.

2. Typical Properties: 
Color Appearance Density Moisture
(@105ºC,2hrs) 		Fineness through 200 mesh PH value
(2%suspension )
Light White Free Flowing Powder 1.6g/cm3 ≤10.0% ≥99% 8.5-10.5
 
3. Typical Applications: 
Water-based paint&coatings
Emulsion paint
Adhesive
Sealant
Cosmetics
Toothpaste
Grout
 
4. Incorporations:
BK-887L can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
 
A.  Water.
B.  BK-887L(Dispersing at high speed shear for 15-30minutes).
C.  Other additives(film-forming agent,dispersing agent,defoaming agent, etc).
D.  Pigment and filler (Mixing and dispersing).
E.  Emulsion (Mixing).
F.  Post correct.
 
5. Recommended Levels:
The amount of BK-887L rheological additive required depends upon the specific system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-1.0% based on the total formulation weight.
 
6. International Countertypes: Bentone®EW/LT, Laporte®WH, Attagel®-50

Aluminum Busbar -
Lightweight, Corrosion-Resistant & Affordable
Huaxin power is your single-source solution for aluminum busbar. We  select the best grades of material at cost-efficient prices, as well as provide quick turnaround time.
Our aluminum busbar can be formed using the same methods as all other materials, which means cost containment and turnaround time are able to be maintained.
Advantages
There are a variety of advantages for using aluminum busbar including:
ï‚·High Corrosion Resistance
ï‚·Good Conductivity
ï‚·Great Heat Exchange
ï‚·Efficient Thermal Dissipation
ï‚·Lightweight
ï‚·Cost Effective
Applications
Aluminum busbar is best utilized for outdoor applications or corrosive, high stress environments.
It is most often used for electrical suppression in low voltage applications, where moderate strength and lightness is required. It`s also ideal for cramped enclosures.
Plating
We have the capabilities and expertise to plate aluminum busbar with tin, nickel or silver.
Tin plating at busbar joints solves oxidation issues. However, silver plating is usually better because it`s tougher and further improves conductivity.
Aluminum Busbar vs Copper
The primary differences between aluminum and copper bus bar is that aluminum is more cost-effective and lighter weight.

Custom Busbar
For demanding or unique applications, Huaxin power provides custom busbar services.
Since aluminum busbar has a structural stiffness that is lower than steel it is offset with a thicker gauge.
