Description

1. Features of LW-99:

1) Environmental Protection: Free of nickel, fluoride and heavy metal;

2) Performance: high corrosion resistance and strong light resistance;

3) Odorless: No smell;

4) Innovation:LW-99 is the initiate in China and opens a new era of nickel-free and fluoride-free sealing products;

5) Stability: The environmental aging tests shows that the profiles with LW-99 sealing exposure in the hot sun by several years , their appearances will be very stable (almost no change).

2. LW-99 compares to the sealing additive containing nickel.

ItemsSpecificationsChemicals	LW-99 Nickel-free andFluoride-free MediumTemperature Sealing Additive	Sealing additiveContaining nickel
Environmental protection	Free of nickel, fluoride and heavy metal;Be in conformity with the EU RoHS directives	Contains nickel,fluoride
Environmental protectiontreatment costs	Less than RMB5 per tone waste water	RMB50-60 per tone waste water
Operation	Simple, just need one kind of additive for bath make-up	It usually takes two or more additives for bath make-up
Adjustment and maintenance	Only need to replenish LW-99 to meet the production requirement, and the solution can adjust PH automatically	PH needs to beadjusted frequently,which will easily make the solution become muddy and aging

3. Bath Make-up:

Name	Quantity	Unit
LW-99	50	g/L
Water or Deionized  Water	Balance	Pure Water

4. Operating Conditions:

Name	Quantity	Unit
LW-99	50-80	g/L
PH	6.7±0.2
Time	1-1.5	min/μm
Temperature	70-75℃

5. Solution Maintenance:

1) Analyze the content of LW-99,PH and bath solution temperature every day. Control them in normal process range;

2) The long-term production using of heating device will cause a little precipitations. Thus, the bath solution should be cleaned regularly according to production conditions.

6. Packaging and Storage:

Package: Plastic barrel (25kg/barrel,1000kg/barrel)  

Storage: Suggested to store in cool, dry and well ventilated place; away from fire and heat source.
