Plastic Repair: Additional Knowledge

Learn everything you need to know about the subject of plastic repair.

Smart Repair brings many advantages for your vehicle repair business and the customer.

• Fast and easy method for most plastic parts (first: identify type of plastic!)

• Can be used for any damage, e.g. holes, scratches and cracks

• One adhesive with TEROSON 150 Primer that works for most types of plastics

• High strength adhesives to meet OEM requirements

• Suitable for over-painting

Practical examples

There are numerous plastic parts on and in a vehicle, which can be repaired. Bumpers represent the majority thereof.

Exterior: Bumpers, fenders, spoilers, hoods, lift gates and trunk lids, roofs, doors, side panels and coverings etc.

Interiors: Lugs and clips on coverings for e.g. doors and pillars

Both are mainly made out of the following plastic types: PP/EPDM, ABS, GRB and PUR.

Plastic Repair for professionals - Numerous plastic parts, like bumpers and lugs can be repaired.

Which plastic can be bonded?


An easy way to find out, whether a specific type of plastic can be bonded or not, is the water-drop-test. Just put a drop of water on the cleaned plastic surface you are going to work with and watch the result:

Plastic Repair for professionals - Do the water-drop-test to check which plastic can be bonded.

a)
• Drop stays in round shape
• Inactive surface
RESULT: NOT BONDABLE without specific pretreatment

b)
• Drop flattens
• Active surface
RESULT: BONDABLE

DO's


Bumpers

•  Due to the bigger dimensions and painted bumpers the repair is even more economical
•  Torn brackets of bumper fixations can also be repaired
• Back side of bumper should be accessible (to apply reinforcement)
• Repairing double panel bumpers with cavities and PUR-foam inserts (e.g. Ford cars) is limited but possible
• Tears up to 10 cm and punctures up to 7 cm can be repaired with good results

Lugs

•  Repairs usually depend on economic viability.
•  Safety aspects have to be taken into consideration

Others

Fender, spoiler, radiator grille, rear view mirror housing or motorcycle fairings
•  These parts can be repaired with excellent results, but the vehicle manufacturers' recommendations and the specific type of damage must be taken into account

DON'Ts


Headlamps/lugs

•  For safety reasons repairs of headlamp housings and broken lugs at predetermined breaking points are not recommended

Fuel tanks

•  Automotive manufacturers strictly forbid any repairs on fuel tanks

Radiator housing

•  The radiator assembly may reach significantly higher temperature

Use of plastics in automotive engineering is growing

•  Lower manufacturing costs
•  Flexible properties and types
•  Reduction of car weight
•  Resistance of corrosion
•  Smoother surfaces through improved design and aerodynamics
•  Noise reduction
•  High potential for development
•  Recycable

Cost savings – insurance companies/customers

•  Insurance companies prefer to repair rather than to replace
•  Lower insurance rates for repairs
•  Customers without comprehensive insurance won't have to spend money on new cars

Opportunity for additional repair shop business

•  Ensure optimal capacity utilisation
•  Profit margin between repair rate and actual cost
•  Improved service attracts new customers

Contribute to environmental conservation

• Reduced fuel consumption, less CO2 output  
• Insufficient recycling capacities
• Energy savings achieved by recycling
• Disposal of discarded parts costs money
• New EG legislation – Recycling Fund (manufacturer/consumer)
