3) DESCRIPTION
STAGE NO.1 : BATCH-RECIPE PREPARATION
Raw materials and Chemicals :-
Fillers
Dry pigment
Surfactant & Dispersant
Vinylester or Epoxy resins
Defoamer
Filler loading

7) WHAT BENEFITS WILL BE GOT
Will produce compounds in Thailand by using the local technical know-how ,in order to set for an initial marketing base .
Will pay Loyalty fee to an actual total sales volume.
The frist Loyalty fee shall be paid within 1 year after the licensee is made and the project has already completed.
Will continue pay Loyalty fee to every 6 months (twice a year) after selling the first lot of local-made products.
For each product received licensee, will maintain product names and send all records pertaining to sales, customers, marketing information for every quarter.
Can sell Vinylester , Epoxy and Additives to make compounds in Thailand.
Will have an additional base in Thailand to make-up a bigger marketing project base in the future.
