1R32 A2 673S High Adhesion Acrylic Acrylic coatings have Excellent electrical properties Easy application Easy repairs Humiseal introduce 1R32 A-2 673S featuring: Adhesion promoters for low surface energy boards High clean solvent mixture for no-clean boards Variants suitable for dip and selective coating Available immediately

1R32 A2 673S High Adhesion Acrylic Low surface energy can be caused by flux residues, or solder resist Surface energy can change after wave solder or reflow This board surface energy 34 – adhesion could be low

1R32 A2 673S High Adhesion Acrylic 1R32A-2 505 1R32A2 673S High adhesion acrylic performs better on low surface energy boards

1R32 A2 673S High Adhesion Acrylic AB Chimie AVR80 Humiseal 1R32A-2 673S Performs well compared to typical competitor material

1B31 NS Gel High Performance Gel Humiseal manufacture various acrylic gels for automated needle and hand dispensing New 1B31NS gel: Available in 55ml cartridges for simplified dispensing Improved solvents to maximise cartridge shelf life Increased flexibility minimises cracking Humiseal 1B31NS gel is available immediately

New Urethane Conformal Coatings Urethanes are excellent coatings Easy solvent application Excellent chemical resistance Low cost coatings 1A33 NS Solvent modified – No Toluene Improved performance in corrosion ‘BONO’test All other performance as for 1A33 Pre-blends available immediately

New Silicone Conformal Coatings Silicones are: Highly tough, flexible coatings Good thermal shock performance Hi temperature stability Humiseal are introducing some new classes of Silicone product 1C49 LV 1C63 UV curable

1C49 LV Low Viscosity Silicon Coating Humiseal Introduce 1C49LV: 500 CPS formulation. Suitable for Asymtek/PVA application. Solvent Free formulation Moisture cure – complete after 60 minutes Hi temperature stability

1C63 UV Curable Silicon Coating Humiseal Introduce 1C63: New UV curable formulation Successful cure with standard UV ovens Secondary Moisture Cure for shadow areas 2000 CPS formulation. Suitable for spray application Hi temperature stability

New Synthetic Rubber Conformal Coatings Synthetic rubber coating have: Excellent flexibility Good temperature stability Easy, solvent based application Humiseal introduce 1B58 Low modulus – suitable under BGA devices Increased flexibility Higher temperature rating – specified to 140oC

New UV Curable Conformal Coatings LV UV coating in development for use with Asymtek Film Coater Product will have: Low Viscosity ~ 65CPS Dual cure mechanism Improved electrical insulation High thermal stability Good adhesion to metal, plastic, resins Good thermal shock performance Hi Cure speed

New UV Curable Conformal Coatings Driving Forces for Low Viscosity UV Conformal Coating Development Speed: High through-put coating equipment can only work with low viscosity materials Accuracy Film coater gives sharp edge definition, hence good accuracy

New Water-Based Conformal Coatings New Acrylic Polyurethane hybrid coating suitable for dip coating –AR6 Product will have: Low Viscosity ~ 80CPS Fast Cure – improved compared with AR1 High chemical stability Good compatibility with no clean processes Already used in Japanese Automotive

New Masking Materials New range of Tapes and Dots Silicone free adhesive Solvent resistant Black tapes/dots are Antistatic
