BRIEF INTRODUCTION
FL Series No-Bake Furan Resin is a kind of environmentally friendly foundry binder. Different types of resins can be used for steel casting, iron casting and non-ferrous casting. They appear pale yellow to red brown transparent liquid with the following characteristics:
A. Low Viscosity This increases the speed of resin addition and fluidity of molding sand.
B. Low Free Formaldehyde Content and Less Order This improves working condition and lightens environment pollution.
C. High Strength This reduces resin addition ratio, which means lower cost and higher quality of castings.
D. Good Collapsibility, High Precision Of Casting With Clear-Cut And Clean Surface This reduces workload for cleaning and improves work efficiency.
DIRECTION FOR USE
A. Mixing Proportion:
Sand 100
Resin 0.6--1.5% of sand weight
Hardener 30%--70% of resin weight
Mixing Process:
Mix sand with hardener using continuous sand mixer or intermittent sand mixer, then add resin and mix evenly. Commonly the mixing time is 5 to 60 seconds. Use sand immediately after mixing evenly.
B. Selection Of Resin Addition Ratio
The addition ratio of resin should be determined by requirement of production. It should be as less as possible if the strength is high enough for production.
C. Stripping Time Control
Stripping time can be adjusted within 10-90 minutes, normally within 15-40 minutes.
D. Curing Speed Control
To quicker curing speed, to improve addition ratio of resin (not excess 70%) or change faster hardener. To slower curing speed, to reduce addition ratio (not under 30%) or change slower hardener.
CAUTIONS
A. Resin and hardener should be stored separately. Strictly prohibit mixing resin and hardener directly to avoid blast!
B. A slight stimulation may be caused if this product contacts with skin. Operator should wear safety articles.
C. Resin should be kept in cold and dry place without direct sunlight. Be careful to handle.

Qingdao On-Billion Industrial Co., Ltd. Was established in 2004 with the approval of China Chamber of Commerce. It's founded on basis of Chemical Business Department of Qingdao Yijia Tongshang Import and Export Co., Ltd, previously named as Qingdao Import and Export Corporation. Its current registered capital is RMB 26 million. As a leading supplier from China, it's honored as the Board Director of Furfural and Furfuryl Alcohol Sub-Association of China Chamber of Commerce of Metals, Minerals and Chemicals Importers and Exporters (CCCMC). It's annual export quantity of Furfural and Furfuryl alcohol has amounted to more than 20, 000mt.
Its main products include Furfuryl alcohol, Furfural, Tetrahydrofurfuryl alcohol (THFA), Silane coupling agents, MOCA, Me-THPA, n-MP, ONT, Titanium Dioxide (TiO2) and PC etc.
It has more than 100 own ISO tanks, easy for recylcing liquid chemicals between China, Korea, Japan and other neighbouring countries. In order to achieve a sustainable development structure and guarantee supply of exported products, it invested and established two joint ventures in recent years. In this way, its industrial construction was stably being carried out. Therefore, its business volume reached USD 100 million in 2012, and it was awarded as one of the top 100 enterprises by export of Qingdao City. Its export market covers more than 20 countries and regions including the United States, Canada, South America, Europe, Africa, Australia, Japan and South Korea etc.
