SizeMagikTM-LP4 - LOW PICK UP ONE-SHOT PRODUCT DESCRIPTION An unique copolymer sizing agent for cotton compact yarn. Special product for air jet loom. Heavy fabric constructions are easier to weave at low-size add-ons using SizeMagik-LP4. The low add-on also permits greater protection on high-speed looms expensive reeds and sensitive mechanical parts life. SPECIFICATIONS 1. Appearance: Off white Granules 2. Solubility: Soluble at 800C 3. Viscosity of 4% solution: 10 to 30 cPs (Brookfield viscometer LVDV II+ pro -Spl.2 , rpm:100 @ 80oc) 4. Ash content (w/w) : Max 3% 5. Bulk density (gm/ml) : 0.65 to 0.85 COOKING METHOD 1. Fill the required quantity of water in the cooker. 2. Gradually sprinkle SizeMagikTM-LP4. 3. Add the required quantity of softener. 4. Close the pressure cooker lid. 5. Open the steam value and cook to @ 120�¯�¿�½?�?�ºC or 35psi. 6. Retain in the cooker for 15 to 20 minutes. 7. Then transfer the size mix to storage. ECONIMICAL ADVANTAGES Yarn abrasion resistance is an important factor affecting weave ability. The friction between the warp to warp and warp to the weft is important in determining the weaving quality. Another important abrasion point in the loom is mechanical parts (Reed, Dropper pin, Heald wire, Weft picking element). Compare with other conventional size mixes and one-shot size products SizeMagik-LP4 gives better abrasion resistance strength. DE-SIZING Easily de-sizable product with hot alkali treatment. STORAGE Keep away from direct sunlight and store in a cool, dry, and well-ventilated place. STABILITY Stable for one year from the date of manufacture. PACKING Available in 50Kg net weight PP bags with moisture-proof liner inside.
Bitumen Primer * Bitumen Primer is Bituminous air curing ready mixed Acid & Alkali resistant special primer. Application * Concrete surface must be clean, dry and rough. No primer should be applied over smooth and wet surface. * After cleaning the concrete surface, one coat of Bitumen Primer should be applied with brush and allow to dry thoroughly. * The drying time will depend upon the temperature. * 24 Month at the temperature 30C (+2OC) Packing * Bitumen Primer: 25 Liter Drum Note * Bitumen Primer contains volatile and slightly toxic solvent. Keep away from spark and open flames at working area. * Bitumen premier it is manufactured using bitumen solution which is used for sealing of prime porous and non-porous surface, and also to protect residential and commercial building. * Bitumen Primer is used to protect substrate against corrosive attack, is suggested to apply anti-corrosive primer.It is best for protection against sub-striate against atmospheric corrosion and chemical corrosion. It is a mixed substance made up of organic liquids that are highly sticky, water proof, viscous,acid proof as with all surface coating, good Bitumen Premier is used for long life of the system. it is applied by brush or roller and allowed to dry before any water proofing treatment so to avoid solvent it is used in defects such as cracks, broken mortar joints, etc. are to be repaired prior to Bitumen primer application.
