Description

Vibration Damping Compound is a water based co-polymer emulsion, with mineral fillers dispersed in a low permeable, polymeric binder. It is solvent free, easy to apply and can be used in most interior and semi-exposed areas.
It is designed to reduce noise by damping resonant vibration caused by continuous or impulsive excitation of the substrate to which it is applied.
Vibration Damping Compound can be sprayed onto smooth and irregular surfaces. Once applied, it has a monolithic spray texture finish.

Applications
Vibration Damping Compound is designed for use in areas where a continuous membrane is required to damp noise and vibration from GRP, steel, aluminium and other non ferrous metals. It is used extensively on large surface areas e.g. floors and bodysides of railway carriages, air conditioning equipment, contoured metal, GRP and other substrate surfaces. Vibration Damping Compound is also ideal as rain screen cladding.

Surface and Air Temperature
Vibration Damping Compound is suitable for used on substrates when the air and surface temperatures is rising between 2℃ and 45℃ and when the air and surface temperature is at least 2℃ above dewpoint.

Fire Performance
Vibration Damping Compound complies with the Class ‘O’ requirements of the Building Regulations, when tested to BS476: Part 6: 1981 and Part 7: 1987
It has also been tested to BS 6853 UK railway standards and has an MI Classification in accordance with French regulation Arrete 28.09.1991

Practical Coverage
Typically, 1 litre of wet compound will cover approximately 0.5㎡ when applied at 3mm wet finish thickness.

Chemical Resistance Vibration Damping Compound is mildly alkaline with a pH between 7 and 9. Storage Vibration Damping Compound should be kept in its airtight container until ready for use. All containers are marked with a batch number and the lower number should be used first. Protect from frost and excessive heat. Avoid exposure to radiant sunlight. Store at temperature between 4℃ and 45℃. Use within six month of purchase.

Method of Application
1	Vibration Damping Compound can be applied to primed, galvanized and stainless steel, aluminium and vitreous enamel surfaces. It should not be applied to bare steel as corrosion will occur.
2	It can be applied inside buildings and most adequately weather protected exterior areas providing it is protected from rain hail and cold winds during application.
3	Inspect substrate prior to application and remove all loose material, flaking paint, rust, oil, grease and any other material likely to impair adhesion.
4	Ensure the surfaces to be treated are clean and dry and mask any surrounding areas to protect from overspray.
5	Stir Vibration Damping Compound thoroughly before use – do not remove excess liquid floating on top of the drum or thin with additives.
6	Apply over large areas using industrial heavy material spray equipment, available from Hodgson & Hodgson Ltd or by trowel over small areas.
7	Spray or trowel on the first coat up to 3mm wet thickness and build up further coats until the required finished thickness is achieved.
8	Allow each coat to dry completely before applying the next. Repair any damage by spraying or troweling over the affected area.

Safety Precautions
1	Ensure the area where Vibration Damping Compound is being applied is well ventilated both during and after the application.
2	It is recommended that gloves, goggles, face mask and barrier cream is worn during application. Avoid contact with skin and eyes and the inhalation of spray mist.
3	Do not smoke, eat or drink whilst applying the material.
4	If it comes into contact with the skin, wash with lukewarm water and soap or a propriety hand cleaner.
5	If it comes into contact with the eyes, wash with plenty of clean water and seek medical attention if irritation persists.
6	If swallowed, rise mouth and throat with water. Drink plenty of water to dilute stomach contents and seek medical assistance.
7	If a spillage occurs, cover with an absorbent material e.g. dry sand, and dispose of it taking care not to contaminate water courses, sewers or soil.
