DeCAL 9380 is a high molecular weight, polyacrylamide-based flocculant which exhibits a very high degree of cationic charge. DeCAL 9380, once inverted and hydrated with water, reacts readily to provide superior floc formation and performance in a variety of solids/liquid separation processes. DeCAL 9380 is supplied in a liquid emulsion form.

2. Applications:

DeCAL 9380 has been designed as a flocculant for a variety of municipal and industrial waste substrates. It has been proven especially effective for conditioning these substrates for solids sedimentation, thickening, and dewatering processes.
DeCAL 9380 offers greatly improved solids/liquid separation efficiencies over a wide range of pH and is available in a variety of packaging for ease of handling and safety.
Recommended solution concentrations: Stock solution 0.75% - 2.0% as supplied Feed solution 1.0% - 0.75% as supplied Recommended storage periods: Product as supplied 6-9 months (mixing of product may be necessary) Stock solution 2 – 5 days Feed solution 1 – 3 days Storage of the concentrated product and solution for longer than the recommended period may be acceptable under ideal conditions though some loss of the product efficiency may occur.
Corrosion towards most standard materials of construction is very low. Stainless steel, glass fibre, polyethylene, polypropylene and rubberised surfaces are recommended as ideal. In some cases aluminium and galvanised surfaces can be adversely affected.

3. Packaging: DeCAL 9380 is supplied in 20 and 200 kg plastic drums and 1000kg semi-bulk containers.

4. Safety & Handling:

DeCAL 9380 exhibits a very low order of toxicity and does not present any abnormal problems in its handling or general use. Standard industrial safety procedures should be observed. Detailed information on handling and any precautions to be observed in the use of the product(s) described in this leaflet can be found in our relevant Material Safety Data Sheet (MSDS).
Storage of the concentrated product should be in a cool dry place and conditions of extreme temperatures should be avoided.
Protect from frost at all times.
Spillages of DeCAL 9380 should be contained and disposed of in accordance with local regulations. Discharges of neat product or solutions of product to waterways should be avoided since some polymeric products may have an adverse effect on the mucous membranes of fish gills.
Solutions of DeCAL 9380 are extremely slippery and caution should be exercised.
Packages should be kept sealed when not in use. Depending upon storage conditions and product age, product separation may occur. If separation is observed, the product should be re-dispersed well by mixing or re-circulation before use to ensure maximum efficiency.

We hope this information will be of value and if necessary we will be glad to offer additional technical advice. Please note that all our information is given in good faith, we can assume no responsibility for any liability incurred. Data and results should be confirmed by the Buyer by testing the product under its intended conditions of use. DeCAL 9380 - Version 0.0 24.09.04
